e6649cc629 i7300_edac: Properly initialize per-csrow memory size
Due to the current edac-core limits, we cannot represent a per-channel
memory size, for FB-DIMM drivers. So, we need to sum-up all values
for each slot, in order to properly represent the total amount of
memory found by the i7300 driver.

1aa4a7b6b0 V4L/DVB: i7300_edac: better initialize page counts
It is still somewhat fake, as the pages may not be on this exact order,
and may even be used in mirror mode, but this is a best guess than the
other random fake values.

b4552aceb3 i7300_edac: Cleanup: reorganize the file contents
This change should do no functional change. It just rearranges the
contents of the c file, in order to make easier to understand and
maintain it.

85580ea4f7 i7300_edac: pre-allocate a buffer used to prepare err messages
Instead of dynamically allocating a buffer for it where needed,
just allocate it once. As we'll use the same buffer also during
fatal and non-fatal errors, is is very risky to dynamically allocate
it during an error.

f427742248 i7300_edac: Cleanup: remove get_error_info logic
As the error logic in this driver came from i5400 driver, it
were using one function to get errors, and another to display.
Let's make it simpler and avoid doing it into two steps.

5de6e07ed7 i7300_edac: Add error detection code for global errors
There's no mention at the datasheet about how to enable global error
reporting. So, I'm assuming that those errors are always enabled.
Maybe I'm plain wrong about that ;)
